493 | /* It's often not enough for our clients to know whether the PC is merely | |
494 | somewhere within the call dummy. They may need to know whether the | |
495 | call dummy has actually completed. (For example, wait_for_inferior | |
496 | wants to know when it should truly stop because the call dummy has | |
497 | completed. If we're single-stepping because of slow watchpoints, | |
498 | then we may find ourselves stopped at the entry of the call dummy, | |

506 | default implementation of CALL_DUMMY_HAS_COMPLETED is sufficient. | |

508 | the presense of multiple breakpoints in its call dummy. | |
